Answer 1

Answer:

1. It is easier row boat in the moving direction of wind.

2. The bicycle tube bursts when it is overfilled with air

3. Air expands on heating and contracts on cooling.

4. The greater the difference in pressure the faster the air moves.

5. A change in the direction of wind is caused due to rotation of earth.

6. The wind from the ocean carry water and bring rain which is a part of water cycle .

7. Uneven heating of land generates monsoon winds from South-West direction in summer.

8. Factors like wind direction, wind speed, temperature and humidity contribute to the development of cyclones.

9. A violent Tornado can travel at the speeds of about 300 km/hr.

10. A whole ___ of India in vulnerable to ___

(A large number of people in India are vulnerable to floods. Or A large number of social groups in India are vulnerable to poverty.)

11. Air around us exerts pressure.

12. The moving air is called wind.

13. The main cause of wind movement is uneven heating.

14. High speed wind can cause cyclone in regions of low pressure.
